Weekly Budget Allocation

Hi,

I have Budget table, date table , sales table ,company table

Company table just got records UK and US and it is mapped with Budget table and Sales table. 

I want to show Weekly budget. Can you please help me to calculate it. On page If i filter company, then it should show only filtered company buget per week. There will be Month and year filter. 

Currently I am calculating 

TotalBudgets=CALCULATE(SUM('Budget[mONTHLYbUDGET]),TREATAS(VALUES(Dates[MonthYear]),'Budget'[MonthYear]))

I am calculating BudgetPerDay =

var BudgetperMonth =CALCULATE([TOTAL BUDGET],FILTER(Dates,Month(dates[Date])=Month(Max(Dates[Date]))),FILTERS(Company[Company]))
RETURN

9ISFILTERED(Dates[Date]),
DIVIDE(BudgetPerDay,[WorkingDaysinMonth],0),[TotalBudget])

Budget table structure and value example.
